Yes I was previously allergic to all of them as well as sulphites and M.S.G.
I got rid of them by correctly my gut dysbiosis and "leaky gut syndrome" that was causing me to develop allergies with lots of supplements and correct diet.
When I ate them I would get all kinds of problems related to a suppressed immune system: pimples, mouth ulcers, frequent colds and flus, and also fatigue, digestive tract upsets and other things I probably wasn't even aware were due to the allergies.
You should get a blood test, if you've been off the foods for long enough the body can desensitise itself to the foods.
